Routing the Lightbar Cable(s):
1. To protect the headliner from damage caused by drilling the cable access hole
through the vehicle roof, allow a 5” to 7” distance between roof and headliner
by lowering the headliner before drilling.
2. Using a 1” hole saw, drill the cable access hole then use a round file to smooth
and de-burr the edges of the hole. Install a 1” grommet (user supplied).
NOTE: There may be a roof support member that spans the distance between
the driver’s and passenger’s side. DO NOT DRILL THROUGH THIS MEMBER!
Adjust the location until the hole can be drilled without contacting this support
member.
3. Insert the cable(s) through the cable access hole into the vehicle. Use RTV
silicone to weatherproof the access hole after the cable(s) are pulled
completely into the vehicle.
4. Route the cable(s) one at a time to their respective destinations (power cable to
vehicle battery; control cable to switch panel). Refer to the instructions included
with your switches for switch wiring information.
IMPORTANT AIR BAG WARNING! Do not install this product or route any
wires in the air bag deployment zone of your vehicle. Equipment mounted or
located in air bag deployment zones will damage or reduce the effectiveness of
the air bag, or become a projectile that could cause serious personal injury or
death. Refer to your vehicle owners manual to learn the air bag deployment
zones for the vehicle. The User/Installer assumes full responsibility to
determine proper mounting location, based on providing ultimate safety to all
passengers inside the vehicle.
Connecting the Power Cable:
WARNING! All customer supplied wires that connect to the positive terminal
of the battery must be sized to supply at least 125% of the maximum operating
current and FUSED at the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!
1. Follow the factory wiring harness through the firewall. It may be necessary to
drill a hole in the firewall. If so, be absolutely sure that there are no components
that could be damaged by drilling. After the hole has been drilled, insert a
grommet to protect the cable.
2. Route the cable along the factory wiring harness towards the battery. Install a
30 amp fuse block (customer supplied) on the end of the RED wire in the power
cable. NOTE: Remove the fuse from the fuse block before connecting any
wires to the battery.
3. Connect the BLACK wire to Chassis Ground.
Connecting the Communication Cable:
Splice the GREEN and GREY wires from the lightbar to the GREEN and GREY wires
from the Controller.
Troubleshooting:
Your lightbar should now be fully operational. If it is not functioning properly, check
your connections for the following:
• The positive wire (RED) is properly connected to the battery, by way of
the user supplied fuse block.
• A working 30 amp fuse is installed in the fuse block.
• The ground wire (BLACK) is properly connected to the factory ground. Be
sure that the wire is fully grounded to this location.
• The two communication wires (GREEN and GREY) are properly
connected to their communication designations.
Refer to your controller instructions for connections and operation.
IMPORTANT! It is the responsibility of the installation technician to make sure
that the installation and operation of this product will not interfere with or
compromise the operation or efficiency of any vehicle equipment!
CAUTION! DO NOT LOOK DIRECTLY AT THESE LED’S WHILE THEY ARE ON.
MOMENTARY BLINDNESS AND/OR EYE DAMAGE COULD RESULT!

NOTE: Mounting straps are made to fit the contours of individual
vehicles. The strap shown is for example only. The strap for your
vehicle may look different. If your lightbar has a 5" mounting foot,
it will assemble differently than the standard mounting foot. It
also uses an extension to compensate for the extra height.
Follow this illustrations for assembly. Mounting to the lightbar
is the same.
